Clarify the difference between pressure dependent and pressure independent systems, and then make a deep dive into this TAB process. There’s a lot of science involved, but in the end, steering and tweaking the process may seem more like an art.
Commissioning professionals, myself included, have always advocated the delay of systems acceptance by and turnover to the owner until the commissioning process is complete. In this sense, “complete” means the systems pass their functional performance tests and the owner’s operations staff has been properly trained.
As the saying goes, the journey of a thousand miles begins with one step. On a data center project, some tailored software can often point things in the right direction. Novices and grizzled veterans alike would be wise to peruse some of these options for maximizing their new construction and retrofit results.
Probably a year before 9/11, I was asked my thoughts along the lines of, “What else should we commission beyond the standard building systems?” My client was the project engineer at the Department of Defense in the Pentagon. I suggested “commission project record drawings.” I guess you could say I made up the task of commissioning record drawings, but I got my point across.
Good IAQ management has become paramount in the construction industry, as study after study shows that employee productivity and health are directly related to the quality of air being delivered inside the workplace environment.
A few months ago, this column covered the basics of developing effective control system sequences. You might recall that it discussed the process of how a designer needs to select and describe sequences that provided safe, reliable, and efficient control.
Integrated Project Delivery (IPD) is a collaborative process that has been applied more and more frequently to building design and construction projects. Although it is implemented in slightly different ways from project to project, it is always about involving all project team members in intense planning and coordination, starting very early in design and extending through construction and facility turnover.
From a missing pipe hanger three floors down to steam traps past their prime, these stories show how steam system problems can originate inside the boiler room or far beyond it. Read more in February issue.
